Two straight lines, whether they're in the same or different planes,

must intersect at either one point or else at no points.

No, two straight lines can intersect at only one point and that is their point of intersection.

Point.

No, that is not true.

In Euclidean plane geometry two infinitely long straight lines intersect at only one point

No. Two lines can include the same point only if they intersect.

Point.

No, only three lines can intersect at a single point.

Perpendicular lines intersect at one point only.

No, that is not true.

Yes.

NO! A linear system can only have one solution (the lines intersect at one point), no solution (the lines are parallel), and infinitely many solutions (the lines are equivalent).

Any number of lines can intersect all at the same point. Think of a circle. Now think of all of its diameters.
